Conductor turns the New York subway system into an interactive string instrument. Using the MTA's actual subway schedule, the piece begins in realtime by spawning trains which departed in the last minute, then continues accelerating through a 24 hour loop. The visuals are based on Massimo Vignelli's 1972 diagram.

Neat — now I want to see Chen turn Santa Monica Boulevard into an oversized sousaphone. You can watch "Conductor" in real time here.
